isne-nonnins-ronn PACKAGE.

Original application filed October 3, 1919, Serial No. 328,311. Divided and this application filed April 12,

To all whom it may concern: Be it known that I, AnnLMnn M. BATES, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in a Bag-Forming- Tube Package, of Which the following is a specification, the subject matter of which is divided out of copending application Ser. No.328,31 1. Y I

My invention relates to a bag forming tube package which can be made up and stored until needed, when it may be placed in posi; tion in a bag filling and forming machine in such wise that as the tube is filled and formed into bags the storedtube will be released from the package only as it is used. Another. object is to provide an arrang ment whereby a relatively great length of.

bag tube may be compressed, carried and stored on a relatively short, spindle or spool, whereby it may be put .in place in a relatively small filling machine and whereby the material to fill the separate successive bags may be introduced through the stored bag tube. Other objects will appear from time to time in the specification.

The subject matter of this present invention is based on material divided out of my pending application Ser. No. 328,311, filed October 3, 1919, and l have illustrated this invention in exactly the same manner as the process now claimedin the other application is illustrated, for the purpose of correlating the two inventions and adding to the ease of understanding them. My invention is diagrammatically illustrated in the accompanying drawings wherein:

Figure 1 is a diagrammatic illustration 40 of one process of making the tubes;

Figure 2 diagrammatically illustrates another process of making, filling and storing the tubes in connection with a single apparatus; L

Figure 3 illustrates a .stored tube in proper condition for use in a bag filling, closing and severing machine;

Fig. 4 is a view of the bottom of the structure shown in Fig. 3.

-Like partsare'indicated by like letters in all the figures. i

' A is a roll of bag making fabric, the two edges of which are gathered together as at B and sewedto form a tube.

Serial No, 373,102.

The finished tube C may be run on to a reel D,-whence, as desired, it may be removed therefrom and placed on a storing tube very much smaller in cross section than the diameter of the finished tube and provided at its lower end with a holding device, whereby a great length of tube may be assembled and retained on a short holding and filling tube.

E is a bag tube forming tube. The cloth of the roll is brought to this tube with its edges together and here they are united, as for example by a sewing machine F. Then the tube is reversed to form the finished tube 5 with a longitudinal seam inside. This tube J in the process of its formation is fed down onto, the storage and filling tube, which is reinovably attached in position. When a suitable length of bag tube has thus been stored it is severed from the roll, or the entire roll may be made into a continuous bag tube. The tube as it is resting on the holder is longitudinally collapsed until it takes the form J and when the entire tube has been put on the holder the funnel J is preferably attached to one end thereof. The other end is provided with an enlargement J which may be of any form, as for example oblong,so as to distend and flatten the tube as shown in dotted lines in Figure 8. J is a tension device or girdle which rests on the enlargement J and under which the end J" of the bag tube passes this girdle may or may not be flexible or elastic as shown.

The result is a finished spool with an enlargement at each end and a length of finished bag making tube threaded and longitudinally collapsed on the body of the spool between the two enlargements. It, as

in'the preferred form. the body of the spool is a tube, then one enlargement assumes the form of a funnel preierablyadaptcd to hold a quantity of material sufficient to fill one of the bags proposed to be formed from the tube, and the other enlargement takes the form of a spreading device which when the bag tube is fed off distends the bag and brings its two sides somewhat closely together so as to facilitate the sewing or closing operation.

These spools or tubes consist therefore of two enlarged ends over. one of which the bag tube may pass with difficulty and a long body portion which is very much smaller in cross section than the distended bag tube, so that the latter can be compressed or puckered or collapsed thereon between the two end enlargements. It would be quite possible, of course, to store the tubes on spools with rod bodies, from which the bag tubes could be subsequently transferred to the filling tubes of the filling machine.

The use and operation of my invention is as follows: I

After the tube which is subsequently to be formed into bags has been made, it becomes necessary to store that tube in such form that it can be transported from the place where it is made to the place where the bags are to be made and filled, and preterably the device upon which the tube is transported and stored is the filling tube through which the material will pass to till the bags and as in actual operation it would be impractical and uneconomical to make a short length of tube, 1 am concerned with the case where a great length of tube is made, as "for example a tube equal in length to the entire length of the roll of fabric. Such tube, since the material must be fed into it from one end to the other, must be compressed within a very short length and this is done by threading and collapsing the tube upon a short storage piece. These filled storage pieces can be transported, stored and used as the case may require, in a machine or by hand, to be converted into tilled bags.

When the stored tubes are to be used, the lower end of the tube is drawn out from under the tension device and pulled down until a proper bag length is released. The lower end then closed and the material is fed into the tunnel above and down through the tube until the ba portion is filled. The tube is then seamed or closed above the bag portion and this part is severed from the rest of the tube to Form the tinished By storage piece I mean. to include any form of device which will serve to hold the bag tube in its collapsed condition. This storage piece might consist of a single rod or a tube or of two or nore rods or anv other convenient arrangement for termini; a spool with small bodv and enlarged ends.
